How to get data from other site - php

Question

I'm making a website and it'll have a user page on which will be user score. I'm taking that score from the other website but the problem is how to do that: how to get text from any element on any website?
I wanted to try this but I don't know how to select that th from which I need text because the whole table hasn't any IDs, only a class. You can see in the code, I want text from the place where is written: I NEED THIS.
Thanks.
<table class="profile" style="padding:0px; margin:0px;">
<tr>
<td valign="top" style="padding:0px; margin:0px;">
<h3>TEXT</h3>
</td>
<td valign="bottom" align="right">
TEXT</br>
TEXT</br>
</td>
</tr>
<tr>
<td valign="top">
<table class="score_stats">
<tr><th>TEXT</th><th> **I NEED THIS** </th></tr>
<tr><td>TEXT</td><td>NUMBER</td></tr>
<tr><td>TEXT</td><td>NUMBER</td></tr>
<tr><td>TEXT</td><td>NUMBER</td></tr>
<tr><td>TEXT</td><td>NUMBER</td></tr>
<tr><td>TEXT</td><td>NUMBER</td></tr>
</table>
</td>
</tr>
</table>

Answer 2

After the whole day of trying I made this:
function getPlayerScore($url){
libxml_use_internal_errors( true );
$dom = new DOMDocument();
$dom->loadHTMLFile( $url );
$finder = new DOMXpath( $dom );
$nodes = $finder->query( "//*[#class='score_stats']/tr" )->item(0)->nodeValue;
$nodes = str_split($nodes, 11);
return $nodes[1];
}
getPlayerScore($user['playercp'])
...and it's working.
